Double-DIN CD-Receivers


2-DIN CD/USB-Receiver with iPod control


Additional images


Kenwood’s DPX504U makes full use of cars which have double-DIN size radios. A large 4-line display gives excellent information in conjunction with its front iPod Direct USB input. A front AUX input is also available for quick connection to portable music players and navigation units. This can be used with the Dual Zone feature to playback only to the rear speakers for example.

On an aesthetic note full colour variable illumination for both the display and the control knobs can be set to match your cars dashboard illumination perfectly. Large easy to understand operation keys and controls knobs make this unit a breeze to use even with the most complicated operations.

For hands-free mobile phone use an optional KDC-BT300 interface is available.
